The above table provides information about New South Wales, Victoria and South Australia. Sustainable diversion limit (SDL) areas not shown in the table may have values relevant to the line item, however, relevant information was not available for the 2012 Account. No information was available to be reported from Queensland or Australian Capital Territory as there are currently no approved groundwater sharing plans for these jurisdictions.

New South Wales water sharing plans, Victorian Water Accounts 2010–11, Upper Ovens River Water Management Plan 2012 and South Australia water allocation plans.

Bureau of Meteorology (the Bureau).

Extractions were extracted from the relevant clauses in the jurisdictional groundwater plans.

The Bureau assumed that the volume of groundwater extracted under other statutory rights is the same as the water requirements estimated for these rights at the commencements of the water management plans.

The volume reported for groundwater extracted under other statutory rights is likely to be underestimated as limited data was available.

The uncertainty estimate was not quantified.

The following changes resulted in the restatement of the 2010–11 year volume:

• scope change
• error correction.

The changes and their respective values are detailed in the following table.

 

Restatement of comparative year information made for the line item 18.7 Groundwater extractions – Other statutory groundwater rights

2011 Account line item	Segment	Volume at 30 June 2011 reported in the 2012 Account (ML)	Volume at 30 June 2011 reported in the 2011 Account (ML)	Difference due to scope change and prior period correction (ML)
18.7 Extraction: other statutory rights	Northern Basin	12,858	12,858	0
	Southern Basin	36,437	10,825	25,612
	Whole region	49,295	23,683	25,612

Scope change was due to the following reason:

• Information on other statutory right extractions for several groundwater management areas and water supply protection areas in Victoria was not included in the 2011 Account. The areas are Alexandra, Barnawatha, Kinglake, Loddon Highlands, Lower Ovens, Mid-Goulburn, Mullindolingong, Upper Ovens, Little Desert, Nhill and unincorporated areas. Information for these areas has been included in the 2012 Account. Resulting volume for this scope change is 18,368 ML.

Prior period error correction was due to the following reasons:

• Information on other statutory right extractions for several Victorian groundwater management areas and water supply protection areas for which entitlement volumes were provided was not included in the 2011 Account. The areas are Katunga, Lower Campaspe valley, Mid-Loddon, Shepparton Irrigation Region, Balrootan, Goroke, Kaniva, Murrayville and Telopea. Information for these areas has been included in the 2012 Account. Resulting volume for this scope change is 6,974 ML.
• Information on other statutory right extractions for Marne Saunders SDL area in South Australia (270 ML) was not included in the 2011 Account.
